CROSSTIE FOR ELECTRIC LOCOMOTIVES.

Application filed October 3, 1927. Serial No. 223,656.

The object of my invention is to make an integral cast metal cross-tie,in which the brake-cylinders form an integral portion of the cross-tie.p.

Y In the accompanying drawings:

Fig. 1 is a sectional planview on the line- 1-1, Fig. 2;

Fig. 2 is a sectional view on the line 2-2, Fig. l;

Fig. 3 is an end View; and

Fig. 4 is a sectional view on the line 1-4, Fig. 2.

This present application is a companion to one filed by me on the 1stday of October, 1927, under VSerial No. 223,343, in which space has beenprovided for the reception of separate brake-cylinders.

In the present instance, the brake-cylinders are an integral part of thestructure.

lThe cross-tie 10, in the present instance, is in the form of anintegral casting and is of sucient depth to form a rigid connectionbetween the two side members of the locomotive frame, the side membersbei ng shown by dotted lines 11, Fig. 2.

The centre bearing 12 is at the upper portion of the cross-tie andprojects slightly above the body of the cross-tie as clearly shown inFig. 2. 13 are the side bearings, which are integral with the structure.111 are the brake-fulcrum which are also made integral with thestructure, and 15 vare integral motor-suspension lugs.

The frame of the cross-tie in the rpresent instance consists oit' alongitudinal central plate 16, side plates 17, and end plat-es V18.There are openings in these several plates so as to lighten thestructure and so that access may be had to the interior of thecross-tie.

The cross-tie is closed at the top by a plate 19 and at the bottom by aplate 20, and connecting the top and bottom plates are trans verseplates 21.

At each end of the structure within the end plates 18 are integralbrake-cylinders 22,

which extend partly below and partly above the top plate 19, as shown inF ig. 2. Within shown in Fig. 4. Bolts secure these heads to the body ofthe cylindersin the presentin stance. f

The cross-tie may be made without the in# tegral motcisuspension lugs,and the crosstie canvbe applied to any rail conveyance, either motivepower, passenger, or freight equipment.

By this invention am enabled to make the lnake-cylinders as integralparts of the cross-tie.

I claim 1. A cross-tie made as an integral casting, having a box-likebody portion; integral side bearings extending above lthe body portion;and horizontally arranged integral brakecylinders located partly aboveand partly below the top plate of the structure.

2. A cross-tie made as a unitary cast structure, having a box-like bodyportion, with a longitudinal internal plate and two transversereinforcing plates at the centre; a centre bearing; side bearings; twointegral brake cylinders, one at each end of the structure; andprojecting brake-hangers, said brakecylinders also being made integralwithvtlie structure. i

3. A Y cross-tie for a locomotive frame,

' made as an integral casting` and arranged to lit between the sideframes ot the locomotive and to form a rigid connection between the twoframes, and having a brake cylinder cast integral therewith. i i

L1. A cross-tie for a locomotive traine, made as an integral castingandrarrang'ed to be located between the side frames of the locomotiveand to be rigidly secured thereto, and having' a brak-e cylinder at eachend thereof cast integral therewith.
